5 Things I Don't Do as a Longevity Doctor

Key wellness strategies / self-care & longevity tips

1. Avoid anticholinergic sleep meds

   • Don’t use Benadryl or “PM” versions of common pain relievers (e.g., Tylenol PM, Advil PM) for sleep.
   • These contain older antihistamines with anticholinergic effects, which can impair thinking and memory.
   • Long-term heavy exposure has been linked to a higher dementia risk (observational evidence—association, not proven causation).
   • Takeaway: If you’re considering OTC sleep aids, be cautious—especially if you’d use them habitually.

2. Let very hot drinks cool down

   • Avoid drinking coffee/tea/soups while scalding hot.
   • Repeated exposure of the esophagus lining to very hot liquids is linked with higher esophageal cancer risk.
   • Mentioned threshold: >65°C / 149°F.
   • Practical cue: coffee shops often serve around 160–180°F—wait for it to cool.

3. Don’t sit completely still on long flights

   • Sitting for hours slows blood flow in leg deep veins, increasing the risk of blood clots.
   • If a clot travels to the lungs, it can cause pulmonary embolism.
   • Action steps:
     • Get up at least once an hour to move.
     • Or flex ankles / contract calves while seated.

4. Be careful with extreme prolonged fasting

   • Don’t do extreme, prolonged fasts solely to trigger autophagy.
   • Much of the strongest autophagy evidence is from animal studies, and it’s unclear how it translates to humans or how long humans would need to fast.
   • Main concern: longer fasts can make it harder to maintain adequate protein, risking muscle mass loss.
   • Clarification:
     • Intermittent fasting / time-restricted eating may help with calorie control.
     • But longer isn’t automatically better for autophagy.

5. Don’t megadose vitamin D without testing

   • Don’t take high-dose vitamin D unless you know your actual blood level.
   • Vitamin D is fat-soluble, so excess can accumulate.
   • High levels can lead to:
     • Calcium problems
     • Kidney stones
     • Abnormal heart rhythms

• No specific presenter name provided in the subtitles.
• Sources mentioned within the subtitles:
  • One observational study on heavy anticholinergic exposure and dementia risk (reported as 54% higher risk for the heaviest exposure group).
• Other referenced content is based on general clinical/medical rationale (e.g., autophagy evidence mainly from animal data) rather than a named publication.
